I've got some bearings on the way to replace one side on my GTi. It's bouncing like crazy and has the 'extra camber' when viewed from behind.
I'm assuming the shaft on which the needles bear will be pitted - as it's pressed in I'm not entertaining trying to replace it.
Instead, I'm going to use Belzona (industrial ceramic metal repair stuff) to fill the pitted surface and polish it back to a reasonable finish.
Thing is, I don't quite get how the rear beam actually works. What stops the lateral force the trailing arm sees when cornering, pushing the arm off the shaft? It can't just be the plate on the end of the anti roll bar surely? It's only held on with 1 screw and that's at the other end of the plate! It seems as if there'd be loads of float on the arm, unless it actually comes up against a thrust face, but I know there isn't one, as I've seen the pictures of the bearings, and both are plain needle rollers. Am I missing something, or just over thinking?
Can anyone help please? I'm fairly confident about tackling this, but for my confusion with how it works.
It's the driver's side I'm doing, so I think I'll need to take the ARB out from the passenger side before I can remove the trailing arm, other than this, it just seems like lots of stuff to remove, then lots of stuff to put back again.
Any tips would be appreciated.
ps. I like the bronze bush idea, needle rollers seem silly to me when there's never any full revolutions of the arm. Even with grease in there, it'll never get worked around properly.

Right, that makes a bit more sense!!!
Thanks!!!
